运用目标回波来识别目标的探讨

本文根据雷达目标脉冲响应的极点不随视角而变的特点,选用目标的固有极点作为目标识别的特征。对于目标回波的极点提取,介绍了时域的Prony法,推导了抵消脉冲法,评价了它们的优缺点。总结以上两种方法,提出了选用上两法的P次多项式的系数为特征的特征参数法,井把性能优良的Burg算法运用于特征参数法中。最后,对这三种方法进行了计算机模拟识别的比较。

A STUDY OF THE TARGET IDENTIFICATION USING TARGET ECHOES

An Approach to the target identification using the target inherent poles as the target signature is described in this paper,based on the fact that the poles of the radar target pulse response do not change with the angle of observation.In respect to the target echo pole extraction the Prony method in the time domain is introduced,and in addition the pulse extinction method is derived.And then,on the basis of comparison between the two methods the signature-parameter method is developed which utilizes the P degree polynomial coefficients of the above methods as the target signature and the excellent performance of the Burg algorithm.Finally the three methods are compared through the computer simulation indentification.
